Abstract: Hot melt processable composition mixtures include an acid-functional (meth)acrylate-based adhesive composition and a zinc di-(meth)acrylate salt. The adhesive composition has a hot melt processing temperature, and the zinc salt has a melting point that is higher than the hot melt processing temperature of the adhesive composition. The mixture is hot melt processable, and upon application to a substrate, the mixture forms an ionically crosslinked layer with thermally reversable ionic crosslinks.

Abstract: A film stack is described. In particular, a film stack that includes a co-extrudable first base substrate, a first pressure sensitive adhesive, a release layer, a second pressure sensitive adhesive, and a second base substrate is described. Such film stacks may benefit from reduced waste, simpler manufacturing, and a thinner overall construction versus conventional film stacks.

Abstract: Film stacks are described. In particular, film stacks including a base overlaminate film layer and a removeable skin layer disposed on the base overlaminate film layer are described. Because the removable skin layer develops haze before the point of irreversibly damaging the base overlaminate layer, the film stack can prevent unintentional overstretching when the film stack is stretched together.
